How to Extend the Service Life of Cylinder Liners?

Methods to Extend the Service Life of Cylinder Liners

When the engine is working, there is high-speed relative motion between the piston and the cylinder liner and the friction is very strong. If not used correctly, it will exacerbate this friction and reduce the service life. Therefore, it is necessary to avoid unreasonable operations, below is some good suggestions,

1, Preheat and start the inkstone, shake and slowly turn it, increase the temperature at idle, start at low gear, and avoid cold starting at low temperatures as much as possible; When the vehicle is difficult to start, try not to use traction to start it. After starting, do not press the accelerator too hard to avoid dry friction between the piston and cylinder liner.

2, Start smoothly and drive at a medium speed to improve usage level; Ensure no overloading, overspeeding, or overloading; It is not advisable to use the combined braking method of shifting gears and turning off the engine when driving downhill. The brake should be used correctly.

3, Pay attention to the function of the thermostat. Regularly maintain the optimal temperature of the engine cooling water to slow down the corrosion and wear of the cylinder.

4, According to technical specifications, mandatory maintenance should be carried out at regular intervals to strengthen the "three filters", improve lubrication conditions, use lubricating and fuel materials reasonably, and reduce cylinder wear.

5, Strengthen the maintenance of the intake system, regularly replace the air filter core, and prevent abrasive wear.

6, Improve the quality of repair and assembly (including cylinder fitting, ring fitting, cleaning, etc.), and strictly follow the technical specifications for cylinder clearance.
